title: The skeleton: the new controller of male fertility?
abstract: Sex steroids, including testosterone, regulate the development and function of the male skeleton. Oury et al. (2011) identify a surprising new connection between the skeleton and the testis, which has implications for male fertility. They show that testosterone production in the testis is directly influenced by the bone-derived hormone osteocalcin.
